The history of Russian Germans (Russlanddeutsche) is one of intensive mobility across space and time. Today, the descendants of eighteenth-century German-speaking settlers in the Russian Empire live on four continents: Europe, Asia, and North and South America. In this volume, authors from the fields of history, sociology, cultural studies, and sociolinguistics analyze key issues of the history and present of this globally connected diaspora group from an interdisciplinary angle. Contributions address the institutional regimes and networks that shapedand continue to shapethe mobility of Russian Germans on a global scale, the impact of war and violence on the history of this group during the ‘;Age of Extremes, ‘ and the language shifts that accompanied their multiple global moves. Its interdisciplinary and geographic diversity makes this volume a unique contribution to research on migration, global diaspora, transnationalism, and practices of belonging. By analyzing the multiple pathways of migration, entanglement, and belonging of people designated as ‘;Russian Germans’ in past and present, its chapters provide fresh insight into the making and unmaking of a global diaspora.
